Spent grains are valuable food by-products of the brewing industry. In Germany, approximately 2 million tons of malted brewing grain is separated after the mashing process each year.<\/p>\n
Small quantities are utilised in foods such as spent grain bread or snacks, with larger quantities used as animal feed. The problem with this by-product, however, is the high water content, and thus limited storability and inefficiency of longer transport routes.<\/p>\n
The aim of the project was the development of a biotechnological process to optimise pig feed in regard to taste, bio-availability, functionality of nutrients and active ingredients as well as the ability to store this valuable by-product.<\/p>\n
A supplementary feed for pigs was tested using fermentation and extrusion technology. Value was added by processing the brewery by-product and residues from oil production by planetary roller extruder. Feeding trials showed that this tasty, durable and ecological feed with a high fibre content had a positive health effect.<\/p>\n","protected":false},"excerpt":{"rendered":"
Domestic by-products can also play a role in replacing soy as pig feed. This means short transport routes and closed material flows. And what could be more local than brewer’s grains?<\/p>\n","protected":false},"author":5,"featured_media":0,"menu_order":3,"comment_status":"closed","ping_status":"closed","template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"portfolio_category":[23],"portfolio_skills":[],"portfolio_tags":[],"class_list":["post-944","avada_portfolio","type-avada_portfolio","status-publish","format-standard","hentry","portfolio_category-projects-completed"],"acf":[],"yoast_head":"\n
